Reference of 189005-44-5 ,Some common heterocyclic compound, 189005-44-5, molecular formula is C17H16N2O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
One proceeds as described in Example 7 except that concentrated sulfuric acid is replaced by 5 ml of concentrated hydrochloric acid and the reaction mixture is refluxed for 5 hours. Thus 21.5 g of methyl-[6-methyl-2-(4-methyl-phenyl)-imidazo[1,2-a]pyridine-3-yl]-acetate are obtained. The product is identical in all respects with the compound prepared according to Example 1.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 189005-44-5, 6-Methyl-2-(4-methylphenyl)imidazol[1,2-a]pyridine-3-acetic acid, other downstream synthetic routes, hurry up and to see.
